I have just been looking at this information about smokeless tobacco on the Cancer research UK website. Aparently all tobacco products contain a cancer causing chemical called 'tobacco-specific nitrosamines' or TSNA for short. The website claims that some smokeless tobacco products 'contain up to 100 times more TSNAs than any other product including cigarettes' but it doesn't specify what these products are.
Are these products snuff or something else? Does anyone know?
The website also states it is a bad idea to use snuff to quit smoking.
